Jurors in the murder trial of Terrell Nicholas and Orlando Kavanaugh are expected to begin deliberating Monday after listening to just over two weeks of testimony from witnesses.

Judge Richard Chin sent the jury home Thursday after hearing from several witnesses who testified to the past criminal activity of Aaron Dorsett, the son of slain Rockland mother Tina Gonsalves and a key witness for prosecutors. Police say Dorsett was in the apartment when Kavanaugh, 30, burst into the family’s Concord Street apartment early on July 8, 2011, and shot Gonsalves in the living room while Nicholas, 27, waited outside in a rented pickup truck.

Defense attorneys have worked throughout the the trial to discredit Dorsett’s account of the shooting, going so far as to suggest Dorsett may have faked evidence to make it look like someone had broken into the home. One witness called Thursday, Evan LeBlanc, testified that Dorsett and his brother attacked him and stole a handgun during a drug deal a year before the Gonsalves shooting.

LeBlanc said he had arranged to meet the Dorsett brothers near the Rockland Place apartment complex on July 20, 2010, to buy marijuana, but was knocked to the ground and robbed by the men when he arrived. He said both men were carrying guns and shot at him when he tried to get away.

LeBlanc said the brothers also stole a gun he was carrying. Police say Dorsett later used the stolen gun, which was presented in the courtroom as evidence, to shoot Kavanaugh during the 2011 home invasion but later lied to investigators about how he got it, claiming he bought it from someone in Brockton.

Aaron and Todd Dorsett were arrested and charged with armed robbery after the incident in 2010, but the charges were dismissed after LeBlanc failed to show up to court.

“I didn’t want anything to do with the trial,” LeBlanc said. “I was embarrassed.”

Kavanaugh and Nicholas have been in custody since they were arrested separately in 2011 and indicted on charges of armed home invasion and murder. Kavanaugh is also charged with armed assault to murder, assault with a dangerous weapon and three firearm-related charges.
